Shifting isssue?
I recently bought my first Trek bike and a bike in general (I have a history of owning bad,.cheap bikes) and so far, I am impressed! The model is SL5 Gen 4.
I have an issue with shifting, particularly on the left side. On Trek website, they claim how "shifting the rear derailleur between cogs (smaller adjustments)", yet for me it does the big adjustements and the left side appears not to do much (I do hear the click when pressing them).
Would anyone be able to explain this to me? I have more questions about the bike, so if anyone is willing to help or chat; my DM is open! Thank you all in advance!
